Also, l is a constant. I would like to request pointers to codes in BOTH
C++ and F 77/90. Further, a description of using the concerned routines
would be GREATLY appreciated. Herein, we have a constraint that at EVERY
point along the trajectory, the relationship x1'(t)^2 + x2'(t)^2 = 1 MUST
HOLD !.

Thanks for your time, and I look forward to recieving a reponse in the near
future.

This program supports a fellowship in the AAAS Mass Media Science and
Engineering Fellows Program.

For a 10-week period in the summer, the AAAS Mass Media Science and
Engineering Fellows Program places advanced students in the natural
and social sciences and engineering at radio stations, television
stations, newspapers, and magazines throughout the United States.

The goal of the program is to strengthen the connections between
science and the media. The fellowship provides scientists and
engineers opportunities to: (1) observe and participate in the process
by which events and ideas become news; (2) improve their communication
skills by learning to describe complex technical subjects in a manner
comprehensible to nonspecialists; and (3) increase their understanding
of editorial decision making and the way in which information is
effectively disseminated. This program is for students pursuing
degrees in the natural and social sciences and engineering. Students
majoring in English, journalism, science journalism, or other
nontechnical fields are not eligible for these fellowships.

SIAM WILL SPONSOR ONE STUDENT FOR A AAAS MASS MEDIA SCIENCE AND
ENGINEERING FELLOWSHIP FOR THE SUMMER OF 2001.

SIAM invites applications from advanced undergraduate and graduate
students and postdocs in applied mathematics and computational
science.

An application form is available from Joanna Littleton in the SIAM office.
You may contact her via e-mail (littleton@siam.org) or telephone
(215-382-9800, Ext.303). In addition to the application form, the student
must also submit writing samples, resume, letters of recommendation, and
academic transcripts to be considered for the Fellowship.

The deadline for receipt of applications is JANUARY 15, 2001.

Please contact Joanna Littleton if you have any questions about this program.

For more information see the Springer page
http://www.springer.de/cgi-bin/search_book.pl?isbn=3-540-66817-9
or the author's page
http://www.informatik.fernuni-hagen.de/thi1/klaus.weihrauch/book.html
with links to Chapters 1 and 4.

For immediate information, here are the blurb and the chapter titles.

The Blurb

Is the exponential function computable? Are union and intersection of
closed subsets of the real plane computable? Are differentiation and
integration computable operators? Is zero finding for complex
polynomials computable? Is the Mandelbrot set decidable? And in
case of computability, what is the computational complexity?
Computable analysis supplies exact definitions for these and many
other similar questions and tries to solve them.

Merging fundamental concepts of analysis and recursion theory to a
new exciting theory, this book provides a solid fundament for
studying various aspects of computability and complexity in analysis.
It is the result of an introductory course given for several years and is
written in a style suitable for graduate-level and senior students in
computer science and mathematics. Many examples illustrate the
new concepts while numerous exercises of varying difficulty extend
the material and stimulate readers to work actively on the text.

This book intends to be an easy, concise, but rather complete
introduction to the ISO/ANSI C++ language, with applications to
object oriented numeric computation for students and professionals
in science and engineering. It introduces concepts, techniques,
and standard libraries of C++ in a manner that is easy to understand
using examples such as vectors, matrices, complex numbers, and
integrals, which are familiar and useful to a typical student or
professonal in science and engineering.

Besides introducing basic and advanced features of C++, the book
contains an introduction and C++ programs for many numeric methods
such as polynomial interpolation, numerical integration, direct and
iterative algorithms for solving systems of linear equations in
real and complex domains, methods for solving nonlinear equations,
ordinary and partial differential equations with real and complex
coefficients. These methods are fundamental in scientific and
engineering computing.

This book gives numerous examples and techniques on how to reduce
(C and Fortran style) run-time overhead and improve program efficiency
and elegancy. Such techniques include function objects (to replace
function call overhead), deferred evaluation for operator overloading,
expression templates, template metaprograms, and replacing certain virtual
functions by templates. It also introduces tools on how to manage source
files, create libraries, and debug and profile programs.

The book can be used as a textbook for students in science and engineering
and a reference book for experienced scientific C++ programmers.

LinAl was designed to bring together C++ and FORTRAN. After all, FORTRAN
is the one and only true language for numerical computations anyway ;-).

At the same time LinAl is supposed to be easy to use, fast and reasonably
save. With respect to the tradeoff between speed and safety, certain
compromises were made, whereby emphasis was put on simplicity and speed.

The library LinAl is based on STL techniques and uses STL containers for the
storage of matrix data and STL algorithms where feasible.

Low level, algebraic operators, linear solvers and eigenvalue solvers are
implemented, based on calls to BLAS, LAPACK and CGSOLX. Implementation of
a Lanzos eigensolver is planned.

LinAl implements algebraic operators (+-*/) for its storage types where
they are meaningful. Additionally, functions to solve linear equation
systems are implemented. The implementation of all computationally intensive
operations is based on calls to LAPACK and BLAS.

LinAl is a small library with an emphasis on speed and ease of use. It does
not provide more than the above one- and two-dimensional arrays. LinAl is not
intended to provide storage container classes for arbitrary data types.
Instead the intention for LinAl is to have a small, fast set of classes that
interface well with existing software libraries such as LAPACK.

LinAl is not intended to compete with Blitz, TNT or Espresso, all of which are
excellent libraries that are strongly recommended to the interested reader.

LinAl was initially created as part of the p-version finite element code AdhoC.

If you are interested in LinAl, visit the LinAl homepage at
http://linal.sourceforge.net/ where you can obtain information about how to
download and use LinAl. Additionally you will find "Open Source" infrastructure,
such as a mailing list and CVS access from the LinAl homepage.

LinAl is published under the LGPL, the lesser general public license of the
GNU project (see www.gnu.org for details). If you need a more liberal
license so that you can incorporate LinAl into your own commercial or
non commercial projects, please drop me a line. LinAl is Copyright 1999-2000

Two postdoctoral positions of ten months are opened in the INRIA C.R.A
COMODE from November 2000. The objective of the action is to investigate the
use of adjoint models and to develop new methods for inverse modeling and data
assimilation mainly in atmospheric sciences. The generic theme is the search for
"optimal observations" (how to choose the location of a measurement
network ? what measurements to do ?).

The first post-doc deals with atmospheric chemistry (common project
between the Air team at ENPC, Paris, and CERFACS in Toulouse). The second
post-doc deals with radiative transfer (common project between the Air Project, INRIA
Paris, and the Air Team, ENPC, Paris).

Motivated candidates must have experience in any or all of the following
categories:
computational science
atmospheric sciences
differentiation tools
adjoint modeling

A post-doctoral research fellow/assistant is required for a period of
18 months, to carry out research on numerical methods for two-phase flows,
in the context of nuclear reactor safefy.

The position has arisen as a result of a succesful bid for a FRAME V European
project. This involves nine European partner organizations. The project, called
ASTAR, has the objective of developing advanced three-dimensional two-phase flow
simulation tools for application to reactor safety. Periodic progress meetings
will be held in various European countries and thus some travelling will be involved.

Candidates are expected have completed a PhD in applied/computational mathematics,
with a strong component on the numerical analysis of hyperbolic conservation laws.
It also expected that candidates be familiar with the physics of compressible
flows, shock waves and mathematical modelling of multiphase flows. The ideal
candidate will have experience with finite volume high-resolution upwind methods
of the Godunov type and as well as a good, recent, publication record in reputable
international journals.

Thesis at the Univ.-Clinic Innsbruck
Financial support: 800 Euro per month + social security
Topic: "Flow and Pressure Simulation in the Lungs"

Candidates background: The candidate for this thesis should have a good
programming background. Knowledge on aerodynamics is desirable but not condition.

Additional information: Different simulation models of the lungs should
be investigated (a lumped parameter model and an aerodynamic model of
the upper airways based on CT-data and V-p-measurements of the lung
segments). We use ACSL and FIDAP-FLUENT for our simulations. Previous
knowledge about these software packages is not necessary. Flow
experiments in pig lungs will be used to validate the simulations.
